Auxiliary Contact Blocks for UKC Contactor Control & Status

The snap-on coupling between the AU block and UKC contactor is engineered as a unified system. Actuator pin depth, spring tension, and latch retention are rigorously verified across the full contactor current range—a level of mechanical compatibility that aftermarket accessories simply cannot provide.

AU blocks configured for safety circuits undergo positively driven contact verification | KRIPAL tests that the mirror contact physically cannot be in the closed state while the main contactor is closed. Test records support your machinery safety validation file.

The silver alloy used in AU block contacts is the same formulation used in UKC main contacts. When your panel uses KRIPAL contactors and AU blocks together, signal circuit contact life characteristics are predictable and documented, not an unknown variable from a mixed-vendor assembly.

Order contactors, overload relays, and auxiliary blocks as a single line item on your purchase order | or as pre-assembled starter kits. One supplier relationship means one quality audit, one set of lead times, and one accounts payable entry per shipment.

KRIPAL holds inventory of your standard AU contact configurations (1NO+1NC, 2NO+2NC, etc.) and ships against your panel production schedule. Your assembly team never waits for auxiliary contacts to complete a panel.

For panel builders exporting machinery to Europe, KRIPAL provides the positively driven contact test data and technical documentation that notified bodies request during safety function validation under the Machinery Directive 2006/42/EC.

Your part numbers and NO/NC contact configuration laser-marked on the AU block body, matching your panel wiring schedule. KRIPAL’s branding does not appear on the component.

Panel designers can communicate directly with KRIPAL engineers for auxiliary contact configuration, safety circuit design reference, and PL-related technical support, reducing intermediate communication steps.
